Wow, that is pretty awesome.
I have some similarities. I am much more agile with sports, especially volleyball. My body responds to move and jump or go where I want it to much more accurately, and I'm jumping higher.
Too funny about being cold though, I'm used to never, ever being cold indoors. Just the other day I was thinking about bumping the thermostat up from 68. Before if the ambient temp was probably 62-64 I was fine. My wife is happy to welcome me to her world.
Coffee I am really struggling with. I cut it out for a while, and with the rest of the diet change and supplements I've slept better than ever. I didn't need it to wake up any more, but on those slow days recently when I needed a boost, I got it from coffee. Now, I'm wanting it every day, but when I have one I don't sleep as well. But man, a good hand pressed double espresso based drink and I can get anything done.
Interesting about thinking about food, I'm luckily not dealing with that. But then again, I eat as much as I want, just not the same foods. I find myself craving healthy stuff now too, except for the occasional burger and fries binge.
Congrats again though, it's well-deserved.
